Prime HD E-Reader - 300dpi, Glare-Free Touchscreen Display 6" Quad-core

Greatly disappointed with this ereader. Advertised as having been updated for 2018 to be the latest and greatest, well I can tell you it ain’t so! I have the Kindle, Nook and Kobo from 2015. And this inkBook, and I would guess it’s the same for any other reader running on Android 4.2 is a dinasor. Very slow and lags horribly when using the Kindle app that I didn’t bother trying the Nook app or Kobo’s. inkBooks app is so basic and lacks many features offered by other readers. The adjustable light temperature is a farce. It goes from a pure white to bright blue white, and the brightness adjustment at the lowest setting is so bright it could be used as a flashlight and the high setting is as bright as the headlight on your car, causing my eyes to hurt. Will no doubt be returning this unit!

Great reader. Open android. Would buy again.

I made the mistake of upgrading from my inkBOOK Prime to the Prime HD. The Prime HD will freeze and restart while using the built-in apps, frequently throw errors when the keyboard, inkBOOK reader, and launcher crash, and when using other applications such as Calibre, will crash or "lose" its default folders. The screen will freeze on the screensaver, and reboot itself rather than unlock. Some of the freezes and crashes happened while under light load (i.e., turning the page) while others occurred when I attempted to wake the device or return back to the launcher home screen. After returning to factory zero, I attempted to simply read using nothing but the basic books and apps that came with it out of the box and found the same errors.Other/Personal Observations: The backlight is simply too bright. The color adjustment is nice enough. The right-side hardware buttons worked smoothly, but the left ones felt like they were off kilter, made a plastic clicking noise and would catch, and would frequently not register. Form factor was comfortable, the screen was clear and easy to read, and the device itself is a good, attractive size.The inkBOOK Prime was a delight, worked fine, and I regret giving it up every moment I pick up the Prime HD. I would go back if I could, but I will end up looking elsewhere for my next Android e-reader unless an inkBOOK Prime magically appears.

Worked ok for a year and a half but then it became unresponsive stuck on last image wont charge or turn off/on. Website has no troubleshooting section and help email only sends demands for pictures and wont give any troubleshooting or advice just repeated demands for picture of issue. Save your money buy from a decent company because if you have an issue you are SOL.

Good

First, I saw that it didn't work well inside the case/cover I bought along with it. After removing it from the case, I noticed other problems: It had trouble maintaining a wi-fi connection with my home network, compared to other devices. Then it had trouble working with my Nook and Kindle accounts and downloading books I already had, especially with the Nook. OK, so it's hard to say how much of that is the device's problem and how much is on B&N and Amazon, but other Android devices I own do better. In fact, I still own and use an inkBOOK Obsidian that I bought a bit over 2 years ago. That device is quirky but doesn't have as many problems as this new one. I think maybe they should bring back the old model, or improve the reliability of this Prime HD. The HD display on the new one is slightly nicer than the one on the Obsidian, but it's not such a huge difference. So I am sending this one back to Amazon and will return to using the Obsidian and/or an LCD display tablet for reading.
